Gambit - Chess Puzzles

One position. One winning move. Find the checkmate. Gambit is a daily chess puzzle built around a single, strict promise: every puzzle is a forced mate in two, three or four, with exactly one first move that works. No "best try", no engine evaluation, no ambiguity. If you find the move, it mates, and the opponent will always play the most stubborn defense available. Tired of ads? App crashes? Dubious data collection and no offline play? So was I. That's how Gambit was born. A NEW PUZZLE EVERY DAY The daily puzzle gets harder as the week goes on: mate in two on Monday, climbing to mate in four by the weekend. Everyone playing on the same date gets the same puzzle, so you can compare notes with a friend. A FORTY-PUZZLE DROP EVERY WEEK Alongside the daily, each week brings a track of forty puzzles that ramps from mate in two through mate in four. Bonus coins at the halfway and the end, to stock up for hints you may need. New drop every Monday. TRACK WHAT YOU EARN Coins for every solve, badges for volume, streaks and depth, and a daily check-in bonus. Integrated with Game Center so you can compete with friends. THE ARCHIVE Missed a day?

Gambit works the same in airplane mode as it does at home. I wanted this on long-haul flights where the wifi was spotty at best. I figure others might, too.
